摘要
在阐述预应力锚索结构及其作用的基础上,分析了影响预应力锚索锚固效果的主要因素,根据现场实测数据,对内锚固段应力分布特征进行了系统的分析,针对预应力锚固效应的三个方面,提出了群锚第一效应和群锚第二效应的概念。
Based on the introduction of the structure and function of prestressed chain, discussion is made on the factors that influence its anchor effect. From the practical data, a systematic analysis is carried out for the distributing characteristics of inner anchor prestressing force section and given the new conception: first group anchor effect and second group anchor effect.
